Stokre with upper limb motor dysfunction EMG-
Conditions
Interventions
The participants in MIT EMG-
NMES will be comfortably seated on the chair,
placed their upper limb on the desk,
and the elbow was flexed and rotated about 90 degrees. According to the study of Park et al (2004),
the attachment sites of electrical stimuli were selected. An active electrode and a reference electrode will be attached to the origin and insertion of the extensor pollicis brevis and the extensor po
and the pad attachment sites were marked using a pen before application. When the electric potential generated through motion imagination reach the set EMG threshold easily during the intervention,
the EMG threshold would be reset to maximize the motion imagination of the affected upper limb. The intensity of the electrical stimulation is determined between 15 and 30 mA to allow sufficient exten
NMES will be applied to the wrist extensor muscle using 3 surface electrodes in the same way as the participants in MIT EMG-
NMES. First,
the voluntary wrist extension of the participant will be induced and the threshold be set based on the level of active potential according to muscle contraction. When the electric potential reache the
biphasic pulses with a frequency of 35 Hz and a pulse width of 200㎲ will be applied for 12 seconds. Then intensity of stimulation is set to be between 15 and 30 mA as in the MIT EMG-
NMES.
